摘要

An adjustable stair and platform system. The apparatus includes a set of stairs which is affixable to a platform at a first height or alternately at a second height. Both the platform unit and the stair unit include vertically adjustable legs above ground engaging feet. The stairs includes a stair rail frame which is releasably affixable to a side hand rail frame provided for the platform unit. The hand rail frame provided for the platform unit includes an end rail which is pivotally mounted to the side hand rail frame. The end rail frame is changeable to support a right hand or a left hand configuration of the side hand rail frame provided on the platform unit. The combination of vertical adjustability, and left and right hand adjustability, make the unit adaptable for various installation configurations, and avoids the need for multiple stair system units for portable buildings.
